The successful recovery of three women missing for years in Cleveland lends hope to parents who are searching for their children. And the Executive Director with the regional office of the National Center for Missing and Exploited Children, Ed Suk, says keeping that hope is very, very important. That's because they're seeing more and more situations where children missing for an extended period of time have been successfully recovered. He says they want parents to maintain that hope until they have answers to what happened to their kids. That includes parents and relatives of Britanee Drexel, the Gates Chili High School student who disappeared over four years ago.
